l ication, accompanied by drawings vforming a part of the same, in'which Figure l is a front view of a pair of eyeglasses embodying-my invention. Figs. 2, 3, 4 and 5 are enlarged views, showing my improved construction of mount for eyeglass and attachment for box stud.

parts in the dillerent views.

' Myinvention relates to a rimless eyeglass having a spring and nose guard held in a box stud attached to one end of the lens, and it comprises an improved apparatus for mounting the lens in order to attach the box stud thereto, consisting in the construction and arrangement of parts as hereinafter described and pointed out in the annexedclaims.

I In the ordinary construction of mount tor a rimless eyeglass in order to attach the box stud thereto, the box' stud itself is provided with airintegral neck, at the end of which are a pair ot parallel arms arranged to embrace the faces of the lens, and. which are held in contact therewith by a screw passing through both arms and the lens itseli'. Integral braces are also provided on either side of the box stud which Contact with the edge of the lens, and are designed to hold the stud from lateral movement on the screw.

f A tight t between the box stud and lens is maintained by tightening the screw and by bending the bracesv as required.

In my improved construction, I provide an elastic member with parallel arms to embrace the end of the lens, and-a screw to hold the arms in position. Movement ot' the member, with reference to the lens, is prevented by elastic braces, arranged to contact with the edge of the lens upon each side of said parallel arms and exert a strain upon the screw in a direction parallel with the longitudinal diameter of the lens, with means for tightening the elastic braces to regulate the amount of strain. ,I also securely attach the box stud to the outer side of the elastic member, and provide means for securing the ends of the spring and nose guard in the box stud.

rboxes 4,

Similar' reference lfigures refer to similar Referring' to the accompanying drawings, 1, 1, are the lenses connected by a spring 2, and having nose guards 3, 3, with the ends of the spring and nose guards held in the 4, in a manner hereinafter pointed out.

The mounting of the lenses, by which the boxes are attached to the lenses, is accomplished as followsz-A cross-shaped blank is -stamped from a suitably elastic material in the torni shown in Fig. 2, having arms 5, 5, with enlarged ends 6. Braces 7, 7, integral-"with the arms 5, extend at right angles thereto, and each brace 7 is provided with an enlargement 8 located at a suitable distance from the arms 5, for a purpose to be later pointed out.

The arms 5 are bent at their point of union, with the braces 7 parallel with the edges of the enlargements 8, arid are then bent approximately parallel to contact with the faces of the lens, as shown in Fig. 5.

The enlarged ends 6 are provided with concentric openings 9 to receive a screw 10.

The side braces 7 are bent at right'angles to the arms 5, upon the dotted lines 11, 11, shown in Fig. 2. A second bend upon the dotted lines 12, 12, ot' Fig.' 2 is imparted to the braces 7, bringing the end otl each bracebeyond the enlargement 8 parallel with the edge of the lens, with which itis designed to contact when the member 13 in position, as shown in Figs. 3, l and The en-` largements 8 of the braces 7 are now oppo site, and concentric openings 14 are vided in the enlargements 8 screw 15, as shownin Fig. 4.

It is apparentthat, when` the member 13 is in position uponrthe edge of the lens, tightening the screw 15 will cause the approach ot' the enlargements 8 and, owing to the elasticity of the braces 7, tend to force the member 13 away from the end of the lens, thereby exerting an outward strain upon the screw 10, which will hold it securely in position and prevent movement of the member 13I with respect to the lens. Before, however, the ymember 13 is placed in position, the box stud i with the usual transverse opening 17 is attached to the surface 18 on the member 13, by solder or equivalent means, as shown in Figs. 4 and 5. A longitudinal hole is then bored through the member 13 and the box stud 4, intersecting the transverse opening 17, for the insertion of a retaining pin 19, as shown by dotted pro to receive a lines in 4 and The inner end of the pin 19 is provided with an eye 20, arranged to be engaged by the screw and thereby held in position. The ends of the springK and nose guards 3, designed to be inserted in the 'opening 17, are provided with openings to receive the pin 19.

ivy improved eyeglass is mounted 'as follows z---r .fter the member 13 has received the form shown in Fig. 3, the box stud attached and the longitudinal hole prepared, the spring' 2 and nose guards 3 are placed in their proper position with their ends overlapping and inserted in the opening 17. The retaining` pin 19 is then inserted into the longitudinal hole, engaging the ends of the spring L, and nose guards 15 is inserted through `he openings 1st in the enlargements S, passing through the eye 2O between them. between the arms employed to bring' the eiilarged ends 6 into contact with the faces of thelens 1. The screw lvis then tightened, andan outward strain is brouigjht upon the screw 10 to hold it securely in position and prevent movement of the member13 upon the lens l. l thus provide a mounting for an eyeglass in which, by the screw 15, the member 13 is held tirinlyaipon the lens, and in which the same screw fis employed to hold the spring Z and nose ,guards 3 securely in the box stud by the pin 19. Removal of this screw loosens the member 13 from the lens, and allows the withdrawal of the pin 19, thereby 'loosening the spring i2 and nose guards 3 in the box stud. The only functions performedby the screw7 10 are holding the ends t3 in contact with the lens and receiving the outward strain upon the member 13 exerted by the elastic braces 7. No tightening of the screw '10 is required. lf for any reason the member 13 becomes loose upon the lens, it can be tightened by tightening the screw 15. No bending of the braces 7 is required after the member 13 has once been formed.
